  Abstract：

  We investigate how people coordinate on public goods provision in a network formation game. In this game, people first form network by bilateral linking, with or without a link cost, and then make contribution to public goods that benefit the people directedly linked in the network. Theoretically, there are two coordination patterns: splitting and alternation, and the latter is more efficient. Further, a higher link cost may help achieve alternation via a smaller network, which can result in higher efficiency. We vary the link cost in the laboratory experiment, and find that people dominantly converge to splitting instead of alternation, and although they tend to build smaller networks when the link cost increases, they fail to alternate even in the two-player network.
